Last year, a Cornell University psychologist named Daryl Bem published a study which he claimed showed that events in the future can influence our minds at the present. I wrote about the study in an essay for the New York Times on the workings of science–how science relies on replication to move forward, and how scientists often struggle to make this happen. When other scientists replicated Bem’s experiments, they failed to get his results. But they found it difficult to get their results published in prominent journals, which frown on replication studies.

Over at Science-Based Medicine, Steve Novella writes about a newly published replication study appearing in the same journal where Bem’s original research was published. Once again, the scientists failed to get Bem’s results. That the future does not affect the present is not exactly news, but Novella’s post is still very much worth reading, because he takes this moment as an opportunity to talk about the reason that studies like Bem’s turn out the way they do in the first place, and how scientists can design experiments better in the future.

Next Friday (August 31) I have the honor of taking part in the Kristine Bonnevie Lecture, an annual lecture held at the University of Oslo to honor the first female professor in Norway. I’ll be speaking along with Cori Bargmann of Rockefeller University, who has done hugely important research on the links between the anatomy of the brain and how animals behave. Details are here.

On Saturday (September 1) I’ll be giving a public lecture about A Planet of Virusesat Oslo’s House of Literature (Litteraturhuset). Details are here.

If there are any Loom-readers in Norway (perhaps a few?), I hope to see you in Oslo.

Two years ago, I wrote in the New York Times about scientists exploring evolution to discover the function of our genes. We share a 1.2 billion-year-old common ancestor with fungi, for example, and it turns out that fungi (yeast in particular) have networks of genes remarkably similar to our own.

Back in 2010, the scientists I interviewed told me they hoped to use this method to find new drugs. In today’s New York Times, I write about how they’ve delivered on that promise. It turns out that a drug that doctors have used for over 40 years to kill fungi can slow the growth of tumors. It’s a striking illustration of how evolution provides a map that allows medical research to find their way to promising new treatments. Check it out.

People have been searching for new medicines for thousands of years, and yet we have barely explored the universe of possibilities. Recently chemists at the University of Bern in Switzerland tried to estimate how many promising molecules have yet to be tested. In June they published their best guess: over a million billion billion billion billion billion billion. Blindly testing those molecules one at a time is not practical, and most of them will turn out to be useless anyway. So many scientists are looking for strategies they can use to zero in more quickly on promising candidates.
